CONTROL SYSTEM
OUTLINE
A6E394018880201
• The control system is essentially carried over from the current Mazda6 (GG), except for the following. (See
Mazda6 Training Manual 3359-1*-02C.)
Vehicle Adoption
4WD ATX model
• TCM has been adopted. Due to this the PCM terminal of ATX device has been replaced to TCM. The ATX
device information which is needed by the fuel and emission control systems is communicated to the PCM by
the controller area network (CAN).
Unleaded (RON 90 or above) model
• BARO sensor has been eliminated. Due to this the BARO factor for purge control has been eliminated.
